50 YOUR TAKE AI
Words by Stefan Lederer, CEO and Founder, Bitmovin
Machine learning could have many practical applications for broadcast workflows. Dynamic encoding is one of them
New publishers like social media companies and news outlets are putting video at the forefront of their content offering. For content owners, players and distributors, this online video revolution is leading to a rethink of the tools they use to enable smooth content delivery to consumers anytime, over any network, to any device. Artificial intelligence (AI) has the potential to address many of the challenges faced by content providers across the entire distribution chain as they aim to deliver the best viewing experience. AI ENCODING Used across production, data analytics and network optimisation, AI is commonly regarded as a solution to speed up and boost the transmission of content, and improve personalisation. However, AI is
also starting to play an important role in encoding, where it has enormous potential to dramatically improve workflows. With the emergence of new codecs, new video file formats and delivery methods, the media industry needs solutions that improve encoding in an automated, immediate and highly efficient way. The use of AI in encoding is a big step forward for the broadcast industry. With the introduction of machine learning, an encoder can make smart decisions about the compression settings and visual parameters for each frame, speeding up processing and improving encoding efficiency. Trained models predict the optimal encoding settings, as well as pre-processing tools, for every given source asset. By continuously learning the parameters used in previous encodes, AI-optimised settings can be applied to
STEFAN LEDERER: AI makes video encoding more dynamic and improves the user experience
ideo has evolved from a medium that audiences engaged with some of the time to one consumed around
the clock. The number of platforms that are video-compatible has also proliferated, encouraging more demand from consumers and, ultimately, new opportunities for broadcasters, content owners and media organisations. The market penetration of internet-enabled mobile devices coupled with rising broadband speeds is encouraging consumers, especially younger demographics, to turn to online video services.
